<h1 class="font-black">Data policy</h1>
<div class="my-4">
Plausible aims to track overall trends in your website traffic, not indivual visitors. With privacy in mind, we dont collect or store any data beyond what is absolutely necessary. Here is a list of what we collect and store about your website visitors.
</div>
<div class="my-4 mt-8">
<h4 class="mb-1">We dont store IP addresses</h4>
We never store IP addresses in our database or logs. The IP address is used to look up the visitor country by Cloudflare, which we store to show the Top Countries report.
</div>
<div class="my-4">
<h4 class="mb-1">We partially store the user-agent</h4>
We use the <code>UserAgent</code> header to figure out what browsers and operating systems your visitors are using. However, the raw user-agent string is discarded and we only store the browser and operating system information.
</div>
<div class="my-4">
<h4 class="mb-1">We partially store the referrer</h4>
Plausible uses the referrer string to show which other websites are driving traffic to the site youre tracking. We store the referrer but we discard all query parameters.
</div>
<div class="my-4">
<h4 class="mb-1">We partially store the page URLs</h4>
We track the URL of each pageview to be able to show the Top Pages report. However, we do not store query strings from the URL.
</div>
<div class="my-4">
<h4 class="mb-1">We store the screen width</h4>
We use <code>window.innerWidth</code> to determine the actual size of the open browser window, rather than the full width of the device. This is more accurate and makes fingerprinting harder.
</div>
<div class="my-8">
<h3 class="mb-2">Cookie policy</h3>
Plausible installs a first-party cooky to be able to differentiate between a new visitor and a returning visitor. This cookie contains a random identifier that is sent along with each pageview request. On the backend, this allows us to aggregate and show unique visitors and total pageviews separately.
